On Sunday (Aug. 14), the singer posted a video to Snapchat of her singing along to a new song in the car. According to MTV, some fans are speculating it’s a collaboration with Diplo as he posted a video of the two in the studio together last week.

In the clip above, Grande uses the butterfly filter as she can be seen lip synching along to the new track.

Meanwhile, last week Grande was shown singing some high notes in the studio with Diplo. While no official collab has been revealed, Grande will likely tease additional new music on her personal Snapchat.
